November 6th, 1982. Just after midnight, the Beverly Sunset Motel, 8775 Sunset Boulevard, Los Angeles. A woman is screaming on the sidewalk. 46 years old, mascara running, bruises blooming on both legs. She is wearing a soiled dress and holding a small purse that contains nothing but a handful of pills, and a phone number she has been dialing for hours.
She staggers into the lobby. She collapses on the carpet. The night clerk thinks she is drunk. She is not drunk. She is dying. Cocaine, Valium, whiskey, a cocktail strong enough to kill a horse already shutting down her organs one by one. 3 days later at Cedar’s Sinai Hospital, Geraldine McGee Rosenthal will be pronounced dead.
The official cause, accidental overdose, the unofficial cause. She knew too much. She ran too late. And the men she had betrayed were not the forgiving kind. This wasn’t just a mob wife. This was the woman Sharon Stone got an Oscar nomination for playing. The woman Martin Scorsesei turned into Ginger McKenna in the movie Casino. But the film softened her.
The film cleaned her up. The real Gary McGee was a Vegas chip hustler who married the most powerful sports better in America, slept with his best friend, kidnapped her own daughter at gunpoint, stole over a million dollars from a safe deposit box that was wired to organized crime, and ended up dead in a roadside motel before her 47th birthday.
The film shows you the affair. The film never shows you the autopsy report. This is the story of how a poor kid from Sherman Oaks became the most dangerous woman in Las Vegas. How she played three of the toughest men in the country against each other and almost got away with it. And why in the end, the desert always collects what it is owed.
But here is what the movie left out. Jerry Rosenthal was not just married to the mob. Geraldine McGee was born in Los Angeles on May 16th, 1936. Her father Roy was an auto mechanic. Her mother Alice was in and out of psychiatric hospitals her entire childhood. The family was, according to her own sister, Barbara, probably the poorest in the entire neighborhood of Sherman Oaks.
While the other girls had ponies and piano lessons, Jerry had handme-downs and a mother who heard voices. She learned two things early. She learned that her face was her ticket out. and she learned that men would give her things if she let them think they had a chance. She filed both of those lessons away.
She would use them for the rest of her life. At Van Ny High School, class of 1954, she was the prettiest girl in the room. She knew it. So did a senior named Lenny Marmmer. Marmmer was charming, opportunistic, and according to multiple sources, a part-time pimp and small-time drug dealer. He saw Gary and he saw merchandise.
He started entering her in beauty contests and swimsuit competitions. She started winning. They had a daughter together in 1958. They named her Robin. Lenny never married Jerry. Lenny never really did anything for Jerry except convince her that the real money was in Las Vegas and that she should go alone.
So, in 1960, with a 2-year-old daughter and a mother who was barely functional, Jerry McGee packed a suitcase and drove east into the desert. She was 24 years old. She had no job. She had no plan. She had a face that stopped traffic and a willingness to do whatever it took. Within 6 months, she was working the casino floor at the Tropicana as a cocktail waitress.
Within a year, she was a chorus showgirl. Within two years, she was something far more profitable. She was a hustler. Here is how the Vegas hustle worked in the early 1960s. A high roller wins big at the craps table. He is drunk. He is generous. He is far from his wife in Cleveland or Cincinnati or wherever. A girl like Jerry walks past.

She smiles. She laughs at his jokes. She lets him buy her a drink. He starts handing her chips. $25 chips. $100 chips, sometimes thousand chips. She thanks him with her eyes. She lets him hold her hand. And at the end of the night, when he is too drunk to remember her name, she walks across the floor, cashes the chips at the cage, and pockets the money. No sex, no promises.
Just a transaction wrapped in flirtation. A good chip hustler could clear $2,000 on a busy Saturday night. Jerry McGee was a great chip hustler. By 1966, she owned her own house. She had bought a car for her mother. She was sending Robin to a private school, and she had the attention of every powerful man in Las Vegas.
One of those men was Frank Rosenthal. They called him Lefty. He was 37 years old, balding, intense, and quite possibly the greatest sports handicapper who ever lived. Lefty did not gamble. Lefty calculated. He had grown up in Chicago, learned the bookmaking trade by the time he was 15, and by his late 20s, he was running point spreads for the outfit.
Lefty did not drink. Lefty did not chase women. Lefty wore custom suits and slept with a calculator next to his bed. But when he saw Jerry McGee walk across the floor of the Stardust, something in him snapped. He pursued her for over a year. He bought her jewelry. He paid off her debts.
He told her she would never have to hustle another drunk again. And on May 4th, 1969, in a small ceremony, Geraldine McGee became Mrs. Frank Rosenthal. She was 33 years old. She thought she had won the lottery. She had no idea she had just walked into a cage. The marriage was poisoned from day one. Lefty wanted a wife, a homemaker, a stay-at-home mom who would raise his children and host dinner parties for casino executives.
Jerry wanted freedom, jewelry, and a credit line at every store on the strip. They had two children together, a son named Steven, born in 1972, a daughter named Stephanie, born two years later. Jerry was not a natural mother. She was a natural performer. the diapers, the school runs, the PTA meetings, none of it suited her. She started drinking.
She started staying out all night. She started using cocaine, which in the Las Vegas of the 1970s was as common as ice water. And then around 1973, she did the one thing Lefty Rosenthal could never forgive. She started sleeping with his best friend, Anthony Spelotro. They called him tough Tony, 5′ 5 in of pure menace from the west side of Chicago. He had grown up with Lefty.
They went to the same schools. They ran the same streets. And in 1971, the Chicago outfit had sent Tony Spelotro to Las Vegas to be their enforcer. His job was simple. Protect the skim. Anybody who threatened the ski got buried in the desert. By the mid 1970s, the FBI suspected Tony Spelotro of personally murdering at least 22 people.
He kept a knife in his sock. He killed a man named Billy McCarthy by putting his head in a vice and squeezing until McCarthy’s eyeball popped out. That was the kind of man Jerry Rosenthal took to bed. And here is what makes the affair so dangerous. Lefty Rosenthal and Tony Spelotro were the two most powerful men in Las Vegas.
Lefty ran the Stardust, the Fremont, the Hosienda, and the Marina casinos under the Argent Corporation. Behind the scenes, he was the guy making sure the outfit got its cut of every dollar that came through the door. Tony was the muscle that kept everyone in line. They were brothers in everything but blood. And Jerry was sleeping with both of them.
Some accounts suggest Tony pursued her first, hoping to gain leverage over Lefty. Other accounts suggest Jerry pursued Tony, hoping to gain leverage over her husband. The truth is probably somewhere in between. What is documented is that by 1976, the affair was the worstkept secret in Las Vegas.
And in the mafia, an open secret is a death sentence waiting for a date. Here is what Lefty Rosenthal did not know yet. While he was secretly informing for the FBI, providing intelligence on the skim operations in exchange for protection, his own wife was doing the exact same thing. According to retired FBI agent Joseph Yablonsky and confirmed in 2015 by the AY’s first female undercover operative in Las Vegas, agents sometimes met with Lefty in one location and Jerry in another.
On the same night, neither knowing about the other. Jerry talked. She talked about the skim. She talked about Tony. She talked about the suitcases of cash that flew out of the stardust counting room every week bound for Kansas City and Chicago. She talked because the FBI promised her protection and because some part of her knew even then that Lefty was going to find out about Tony and when he did, she was going to need somewhere to run.
The collapse started in 1979. The Nevada Gaming Control Board denied Lefty Rosenthal a gaming license. 20 years of FBI surveillance, congressional testimony, and mob skimming finally caught up with him. He was officially banned from the casinos he had built. He fought it in court. He hosted a bizarre talk show called the Frank Rosenthal Show, broadcast from the Stardust, where he interviewed celebrities and openly mocked the gaming board.
None of it worked. By 1980, his power was crumbling. And as Lefty’s power crumbled, Jerry saw her exit. September 1980, Las Vegas Country Club Estates, a gated community where the casino bosses lived. Jerry Rosenthal had been drinking for most of the day. Lefty had locked her out of the house. She stood on the front lawn screaming.
Then she pulled a gun, a chromeplated 38 caliber snubbed nose with her name engraved on the pearl handle. Lefty had given it to her himself years earlier. She waved it at the house. She waved it at the neighbors. She threatened to kill her husband. The police were called. Nancy Spelotro, Tony’s wife, was the one who calmly walked over and took the gun out of Jerry’s hand.
Think about that for a moment. The wife of the mob enforcer disarming the wife of the casino boss while the neighbors watched from behind their curtains. That was Las Vegas in 1980. That was the kind of life Gary was living. 3 months later, Jerry made her move. She drove to the Valley Bank of Nevada.
She opened the safe deposit box that she and Lefty shared, and she took everything, the jewelry, the cash. According to several sources who had access to the Pelgi research files for the book Casino, the total value of what she removed approached $1 million. Some say it was higher. Some say it was as much as 3 million when you counted the cash, the jewelry, and the bearer bonds.
She loaded it into her Mercedes. She drove to her daughter Robin’s school, and she did something that almost no mob wife had ever done before. She kidnapped her own child. >> My daughter’s with him, too, and I think they’re going to try and kidnap us. >> Here is the scene as it was later reconstructed by FBI agents.
Jerry pulled Robin out of class without authorization. She drove straight to McCarron International Airport. She bought two tickets to Los Angeles. Cash. She did not tell Lefty. She did not call her son or her younger daughter. She left them behind in a house with a man she believed was about to kill her. Robin was confused, terrified, asking why they were leaving.
Jerry told her they were going on vacation. The plane took off. By the time Lefty Rosenthal got home that night, his wife was gone, his oldest daughter was gone, his safe deposit box was empty, and the divorce papers were already being drawn up. The divorce was finalized on January 16th, 1981.
Lefty got custody of Steven and Stephanie. Jerry got $5,000 a month in alimony, the Mercedes, and the jewelry. Officially unofficially, she had already taken everything she could carry. She moved to Los Angeles. She rented an apartment in the Hollywood Hills. And she started spending money like a woman who knew she did not have much time left to spend it.
This is where the story gets dark. And this is where the movie Casino lies to you. In 1981 and 1982, Jerry McGee did not retire. She did not raise her daughter. She did not start a new life. She fell apart. She started running with a biker crowd in Hollywood. Hell’s Angels, drug dealers, low-level pornographers.
She was using cocaine daily by then. She was drinking a fifth of whiskey a day. And then, almost inevitably, she ran back to Lenny Marmmer, the same Lenny Marmmer who had pimped her out in beauty contests when she was 17. The same Lenny Marmer who had abandoned her with a baby in Las Vegas 20 years earlier. He was waiting for her in Los Angeles, and he had a plan for her money.
Within 6 months, the jewelry was gone. Marmmer took it piece by piece, supposedly to sell at favorable prices, returning with a fraction of what it was worth. The cash was burning faster than she could track. The $5,000 alimony checks from Lefty were not even covering the cocaine bills. Jerry was sleeping with murmur, fighting with murmur, and according to her sister Barbara, being beaten regularly by Marmmer.
Her daughter Robin, now 23 years old, watched the whole thing from a distance. The mother, who had kidnapped her at gunpoint to save her life, was now being slowly destroyed by a man even Jerry’s own family considered a predator. And back in Las Vegas, Lefty Rosenthal was preparing for the end. October 4th, 1982. Tony Roma’s restaurant, 600 East Sahara Avenue, Las Vegas. Just after 8:00 p.m.
, Lefty Rosenthal finished his meal, walked out to his 1981 Cadillac Elorado, and turned the key. The explosion lifted the car 3 ft off the ground. The blast shattered windows 50 ft away. The undercarriage was completely destroyed. By every law of physics, Lefty Rosenthal should have died in that car. He did not.
The Cadillac had been built with a metal plate under the driver’s seat, a factory anti-corrosion plate. That single piece of steel absorbed enough of the upward blast to save his life. Lefty walked away with burns and a broken eardrum. He went into hiding the next day. He believed Tony Spelotro had ordered the hit. He was probably right. When Jerry McGee heard about the car bombing in Los Angeles, something in her finally broke. She knew what it meant.
The outfit was cleaning house. Lefty was marked. Tony was marked. And as the woman who had slept with both of them, who had FBI files in two different field offices, who knew where the skim money was hidden and how it moved, she was marked too. According to her sister Barbara, Jerry started making frantic phone calls. She called Lefty.
She begged him to take her back. She told him she was sorry. She told him she was scared. She told him Lenny Marmer was stealing what was left of her money. She told him she would do anything if he would just send someone to come get her. Lefty refused. He told her she had made her choice. He hung up the phone.
He would later tell investigators that it was the last conversation he ever had with his wife. Some say she called him a second time 2 days before her death, screaming and crying, begging for protection. Lefty has always denied this. What is documented is that in the final week of her life, Jerry McGee was a 46-year-old woman with no money, no protection, a drug habit that was killing her, and the knowledge that the most dangerous men in America considered her a loose end.
On November 6th, 1982, just after midnight, Jerry McGee walked into the lobby of the Beverly Sunset Motel and collapsed. The motel was a step above a flop house. She had been staying there for several days, in and out, with Lenny Marmmer coming and going. The legs that had once carried her across the stage at the Tropicana were bruised black and purple.
Her dress was torn. She was incoherent. The night clerk called an ambulance. Paramedics found her pulse barely registering. They rushed her to Cedar’s Sinai. She never regained consciousness. For 3 days, the machines kept her alive while doctors tried to flush the chemicals from her bloodstream. It did not work. On November 9th, 1982, at the age of 46, Geraldine McGee Rosenthal was pronounced dead.
The autopsy was performed by the Los Angeles County Coroner. The toxicology report showed three substances at lethal levels. Cocaine, Valium, whiskey. The official ruling, accidental overdose. Case closed. But the case was not closed for everyone. Her sister Barbara never accepted the accidental ruling. She believed Jerry had been murdered.
She believed the cocktail of drugs had been forced on her or administered while she was already incapacitated by people sent to make sure she could not testify to anything. The timing was suspicious. Just 33 days after the attempt on Lefty’s life, the location was suspicious. A motel where she had been seen arguing with Lenny Marmer.
The cause was almost too perfect. A known drug addict overdosing on her drugs of choice. Who would investigate that? Nobody did. The LAPD closed the file in under a week. The FBI, despite knowing she had been one of their informants, did not open a parallel investigation. Lenny Marmmer was questioned briefly and released. He was never charged with anything related to her death.
He continued to live in Los Angeles, allegedly with the remaining cash and jewelry he had taken from her for years afterward. Four years later, the rest of the story finished writing itself. June 23rd, 1986. Tony Spelotro and his brother Michael were lured to a basement in Bensonville, Illinois. They were beaten to death with fists and feet by their own crew.
Their bodies were buried in a corn field in Indiana, where they were discovered 9 days later by a farmer plowing his land. Tony Spelotro was 48 years old when he died. The Chicago outfit had decided he was bringing too much heat. The skim was already collapsing because of the FBI investigation.
Lefty and Jerry had both been feeding for years. Lefty Rosenthal survived. He moved to Florida. He ran an offshore sports betting operation. He never remarried. He raised Steven and Stephanie alone. He gave one interview about Jerry and the entire rest of his life, telling Nicholas Pelgi for the book Casino that he had loved her and she had destroyed him and that was the whole story.
Lefty died of a heart attack in his Miami Beach home on October 13th, 2008. He was 79 years old. Their daughter Stephanie has rarely spoken publicly. Their son Steven has stayed out of the spotlight entirely. Robin Marmmer, the daughter Jerry, kidnapped at gunpoint in 1981, lived a quiet life and reportedly struggled for years with the trauma of being raised by a mother she both loved and feared.
So, what was Jerry McGee really? Not the seductive party girl Sharon Stone played on screen. Not the helpless victim of a controlling husband. Not the misunderstood mother fighting for her freedom. She was all of those things and none of those things. She was a poor kid from Sherman Oaks who learned at 14 that her face was a weapon and never stopped using it. She married up.
She slept across. She informed sideways. She kidnapped her own child. She stole over a million dollars from one of the most dangerous organizations on earth. And then she did the one thing nobody in her position can afford to do. She fell in love with a man who was using her. She got high. She got slow. She got isolated.
And the moment she became useless to everyone, the moment she had nothing left to trade, the desert came back to collect. The film shows you the glamour. The film shows you Sharon Stone in a sequin dress on the casino floor. The film does not show you a 46-year-old woman bleeding internally on the carpet of a Sunset Boulevard motel, dialing a phone number that nobody is going to answer. That is the real ending.
That is the real Jerry McGee, a woman who played the most dangerous game in America for 20 years and almost won. Almost. Because in Las Vegas, almost is just a slower way of losing everything. And Jerry McGee lost everything. her marriage, her children, her money, her life. The only thing she kept was the legend.
And the legend in the end belongs to Sharon Stone. If you found this story as dark as we did, hit subscribe. We drop a new mob documentary every week. And in the comments, tell us this.
